Hap files media moved, later replaced into project and refreshed Inspector, but cant play

Hi, has anyone experienced this, maybe moving Hap files out of a media folder, realising they are missing for some projects so move them back, but their icon remains a generic QT file icon ( no thumbail ) the filenames have not been edited/… so when i use Windows media inspector and refresh the folder with them, they cant be played. The Preview windows for all 4 layers remain black… ive restarted etc… the file sizes are same… what could be going on here ? thanks

Can you play the files back in another media play? VLC or IINA?
